"What is the best way to brush teeth?"

Proper brushing removes plaque from the inner, outer and chewing surfaces.  Place toothbrush at a 45 degree angle; start along gum line with a soft bristle brush in a gentle circular motion. Brush the outer surfaces of each tooth, upper and lower. Repeat the same method on the inside surfaces and chewing surfaces of all the teeth. Finish by brushing the tongue to help freshen breath and remove bacteria.
